Figures 1 A−G, 4.

Type material. Holotype: male from Jardin Botánico del Darién (8°37′53.95″N; 77° 21′23.43″W), 90m, Acandí, Capurgana, Chocó, Colombia, 28.III.2009, M. Vargas & C. Zornasa leg. ( MPUJ _ ENT 0061936 ) . Paratypes: one male and female same data as holotype ( MPUJ _ ENT 0061923 [m#1]; MPUJ _ ENT 0061910 [f#1]); one male and female same locality data, 250m, 7.X.2009 ( MPUJ _ ENT 0061884 [m#1]; MPUJ _ ENT 0061897 [f#1]). One male same locality data, 3.XI.2008, J. Aristizabal leg. ( IBSP 244556 ) .

Etymology. The specific epithet is a patronymic given in honor of the Spanish singer Alejandro Sanz, who has greatly contributed to Spanish music.

Diagnosis. Males of Macrophyes sanzi n. sp., resemble those of M. elongata Chickering, 1937 by the conical ventral tegular process and a retrolateral tibial apophysis with a small posterior projection (see Brescovit 1992, figs 6, 7), but can be distinguished by the quadrangular, straight retrolateral tibial apophysis and wider ventral tegular process ( Figs 1 C−E). Females are similar to those of M. elongata by having an oval atrium, differing mainly by their rounded and large spermathecae. Also, resembles to M. pacoti Brescovit et al., 2019 by the large and rounded spermathecae, separating by the shape of the atrium ( Figs 1F, G ).
